FRED ARTHUR GREEK, OF RUSHVILLE, ILLINOIS.

DRAFT-EQUALIZER.'

SPECIFICATION forming part of Letters Patent No. 367,099. dated July 26, 1887.

Application filedMay 17, 1887. Seiial No. 238,531. (No model) To all whom it may concern:

Be it known that I, FRED ARTHUR GREER, a citizen of the United States, residing at Rushville, in the county of Schuyler and State of Illinois, have invented new and useful Improvements in Draft-Equalizers. of which the following is a specification. v I

My invention relates to-improvements in draft-equalizers adapted for three horses; and it consists in a certain novel construction and arrangement of parts for service, fully set forth hereinafter, and specifically pointed out in the appended claims.

In the drawings hereto annexed, Figure 1 is a plan view of my improved equalizer. Fig. 2 is a view in elevation of Fig. 1.

Referring by letter to the drawings, A designates the draft-beam, to which are pivoted two laterally-extending levers, B 0, having the singletrees B attached to the extremities thereof.

D designates an equalizing-bar pivoted at an intermediate point of its length tothe draftbeam in rear of the levers B O, the said bar having a long arm, cl, extending outwardly from the graint and having a singletree, D, at

- tached thereto by a link, D and a short arm,

relative positions.

cl, to the extremity of'which is attached the pulley E.

G represents a draft-chain, secured at one' The levers B and 0 being separate, the strain brought upon one of them by the draft-animal willbe equalized by the animal attached to the other lever, the draft-chain acting as the medium through which said equalization takes place; and as the levers are of equal lengths and the distance from the end ofthe lever O'to the pulley is much greater than the distance from the extremity of the lever B to the pulley, it is evident that it would require a greater amount of force to be applied to the end of the said lever C than to the end of the lever B to maintain said levers in their proper To obviate this, I attach the draft-chain to an intermediate point of the said lever 0, thus giving the draft-animal at tached thereto greater leverage than the one attached to the lever B. This enables two animals of about equal strength to exactly bal auce each other in the draft.

It has been usual heretofore to attach the pulley around which the draft-chain operates either to the draft -beam or to a stationary pointas a yoke or bracket attached to the said beamand for various reasons it has been objectionable. In my improved equalizer I attach the said pulley to the extremity of an equalizingbaepivoted to the said draft-beam, and counterbalance the strain brought upon the said extremity by attaching another draft animal to the extremity of the opposite and longer arm of the same lever or bar, thus accurately balancing the draft and producing a perfect equalizer.

I am aware that it is not new to use laterally-extending levers pivoted to the draftbeam, and also that it is not new to use a draftchain secured to the said levers and passing around a pulley; but the peculiar arrangement herein described I claim to be new, as hereinafter set forth.

Having now described the construction, operation, and advantages of my invention, what I claim, and desire to secure by Letters Patent of the United States, is y 1. In a draft-equalizer, the draft-beam A and levers B O, pivoted thereto, having singletrees B G, combined with the equalizingbar D, pivoted at an intermediate point to the beam A, the singletree D, attached to one arm of the bar D, the pulley E, secured to the other arm, and the draft-chain G, passing around the said pulley and attached at the ends to the said levers B O, substantially as and for the purpose set forth. r

2. In a draft-equalizer, the combination of the draft-beam A, levers B O, of equal lengths, pivotedthereto, singletrees B O, secured to the extremities of the levers, equalizing-bar D, pivoted to the draft-beam and having unequal arms (2 cl, to the longer of which is attached the singletree D, and to the shorter of which is attached the pulley E, and the chain IOO 3. In a draft-equalizer, the combination, with the draft-bean1 A and levers B O, pivoted thereto, of the pivoted eqnalizin -bar D, hav- 1 w V P 4 ing a pulley thereon, and the daft-chain at- FEM) Arm GRLDR' 5 inched to the said levers and passing around the pulley, substantially as described.

In testimony that I claim the foregoing as my own I have hereto alfixed my signature in presence of two witnesses.
